Chapter 25 (digital imaging)
A detector that is used to capture the dental image
Sensor
digital imaging systems can be used for which images? a. bitewing b. panoramic c. cephalometric d. all the above
bitewing, panoramic, and cephalometric
An image receptor found in the intraoral sensor
charge coupled device
digital imaging can be used for
detecting conditions of teeth and surrounding structures, evaluating the growth and development of jaws, confirmation of suspected disease
A filmless imaging system; a method of capturing a radiographic image using a sensor, breaking the image into electronic pieces, and presenting and storing the image using a computer
digital radiography
A method of reversing the gray scale as a digital image is viewed
digital subtraction
To convert an image into digital form that, in turn, can be processed by a computer
digitize
A method of obtaining a digital image in which an intraoral sensor is exposed to x-rays to capture an image that can be viewed on a computer monitor
direct digital imaging
All intraoral sensors can be heat sterilized after used
false
digital imaging requires more x-radiation than conventional radiography
false
in digital imaging, the term used to describe the picture that is produced is called a radiograph
false
a discrete unit of information; a picture element
pixel
A form of indirect digital imagine in which the image is recorded on phosphor coated plates and then placed into an electronic processor, where a laser scans the plate and produces an image on a computer screen
storage phosphor imaging
digital imaging requires less radiation than does conventional radiography because:
the sensor is more sensitive to x-rays
What is a disadvantage of digital imaging
the size of the intraoral sensor.
The preferred exposure method for intraoral digital imaging is the paralleling technique
true
compared with film emulsion, the pixels used in digital imaging are structured in an orderly arrangement.
true
digital subtraction is an advantage in digital imaging because distracting background information is eliminated from the image
true
one advantage of the digital imaging system is the superior gray-scale resolution that results
true
the manipulated o the original digital image can be considered a legal issue
true
the x-radiation source used in most digital imaging systems is a conventional dental x-ray unit
true
Digital imaging was introduced into dentistry in what year?
1987
the image receptor found in the intramural sensor is termed:
CCD (charge-coupled device)
